PURPOSE: To improve a specular property by increasing the density of a metal powder sintered compact.

CONSTITUTION: The compact body is obtained by executing injection molding or compacting to the mixture of metal powder and org. material, and then the compact body is degreased and sintered to obtain a metallic sintered compact. Then, the sintered compact is subjected to a hot forging or a cold forging to reduce pores and to increase density. When the density of the sintered compact is increased, the specular property is improved and the worth as an arnament is elevated.
